[bug] Box upgrade in 3.1.0 causes DynaBox signature change and broke existing code

Hi @rochacbruno

Describe the bug

I was using the following code in an existing module, and the 3.1.0 release causes an error due to 0e4752a979be8cd5f872a06d049886e589dc7da8 (59be115724f9d973229bc8e1b884a3ae3e4f9bd5) updating Box, which now requires the box_settings keyword argument.

>       data = DynaBox(settings.as_dict(internal=False))
E       TypeError: __new__() missing 1 required keyword-only argument: 'box_settings'

To Reproduce

pip install dynaconf==3.1.0

# contents of error.py
from dynaconf import settings
from dynaconf.utils.boxing import DynaBox

data = DynaBox(settings.as_dict())

# Traceback python error.py
(dynaconf) ➜  dynaconf git:(master) ✗ python error.py 
Traceback (most recent call last):
  File "error.py", line 5, in <module>
    data = DynaBox(settings.as_dict())
TypeError: __new__() missing 1 required keyword-only argument: 'box_settings'

(dynaconf) ➜  dynaconf git:(master) ✗ pip list
Package    Version
---------- -------
dynaconf   3.1.0
pip        20.1
setuptools 46.1.3
wheel      0.34.2

Expected behavior

Should I add a default argument for box_settings for dynaconf versions >=3.1.0? Is DynaBox considered private? Or is this a bug and will DynaBox provide a default argument for box_settings in Box.__new__?

Cheers, Andreas 😃

@ap-- Your title is fine!

We have 2 problems here:

1. You should be able to instantiate DynaBox without passing a box_settings argument.
2. If python-box is installed in the system (externally) it overrides the vendored version

I will work on fixing it ASAP
